Randomized, controlled trial of insulin for acute poststroke hyperglycemia

Abstract

GKI infusion within 24 hours of stroke lowered blood glucose and attenuated an increase in brain lactate, but did not affect cerebral infarct growth. Exploratory analysis found that GKI infusion was associated with greater infarct growth in patients with persistent arterial occlusion, and with a high incidence of asymptomatic hypoglycemia.
